How do you read a carrier nomenclature?
How do you read a carrier nomenclature?
Carrier/Payne/Bryant Carrier systems made in the last 20 years or so encode the week and year of manufacture within the first 4 digits. The first 2 are the week of the year (1-52) and the second are the year. For example 0199 would mean the system was made the first week of January in 1999.
How do you read a carrier tonnage?
Look for the 7th and 8th digits, or maybe 8th and 9th digits, of the model number. It will be a number divisible by 6 or 12, and represents the nominal BTU of the system in thousands. A ton of air conditioning equals 12,000 BTU, and 48 divided by 12 equals 4, so the data plate below indicates the system is 4 tons.
What year is my carrier unit?
The most common way to to determine the carrier ac age is through the serial number. In the above style, the determining factor is having a letter in the middle of the serial number. The first two digits are the week of manufacturer. The second set of digits are the year of manufacture.
How do I know the tonnage of my AC carrier?
Find the model number. Within this string of letters and numerals, you should find an even, two-digit number. The possibilities on residential units range from 18 to 60. Divide the number by 12 (which represents 12,000 Btu/hr, or one ton of cooling capacity) to get your AC unit’s tonnage.
What is tonnage in HVAC?
Tonnage is actually a measure of how powerful an AC is at cooling down a space. Tons are units of cooling power, so when we say that a system is a “two ton” or “five ton” unit, we’re indicating how powerful it is, not its weight. One ton = 12,000 BTUs of heat removed per hour from a space.
What tonnage AC do I need?
To estimate your AC tonnage needs, multiply the number of square feet you’re cooling times 25. This equals the total number of BTUs you need to adequately cool your space. Next, divide that number by 12,000 to determine the tonnage capability you need in your new air conditioning unit.
How do you determine the tonnage of a Carrier AC unit?
Why do we calculate AC tonnage?
The use of tons to measure cooling capacity comes from this time. A ton refers to the amount of heat it takes to completely melt a ton of ice. The capacity of an air conditioner refers to the amount of heat it can remove. Rounding up 11,917 Btu/hr gives you 12,000 Btu/hr, which is one ton of air conditioner capacity.
